Division HOCHTIEF Americas

The HOCHTIEF Americas division brings together the activities of our four North American subsidiaries—Turner, Flatiron,
E.E. Cruz, and Clark Builders. These companies provide building and infrastructure construction services primarily in
the U.S. and Canada, each of them focusing on different aspects. Their activities span market segments such as public
buildings, office properties, sports facilities, educational and healthcare properties, transportation infrastructure,
hydroelectric power stations, and dams. Close cooperation between our companies in the North American market allows
them to benefit from synergies as well as from a steady exchange of information and experience.

our companies’ proximity to markets as well as their focus on quality and results was once again recognized with numerous
awards. Turner remains the U.S. number one general builder: In the 2016 rankings published by Engineering News-Record (ENR),
the company continues to hold first place in commercial/industrial building construction. Overall, Turner is listed in more
than 20 ENR categories, consolidating its top position in the markets for office, hotel, educational, healthcare, and
entertainment properties as well as pharmaceutical construction. Turner is also the leader in the construction of green
buildings, generating more than twice the sales of the company ranked second by ENR.

More information:

Our infrastructure specialist Flatiron is rated fifth in the ENR ranking for highway construction and eighth for the
construction of transportation infrastructure and bridge projects. This puts Flatiron in a strong market position that
is to be expanded still further.

Both Turner and Flatiron have in-house engineering units. In order to manage and minimize risks, the Turner Engineering
Group and the Flatiron Technical Services Group act as competence centers on projects, preparing, reviewing, and optimizing
planning as needed.

Turner is among the United States’ leading providers of virtual design and construction, also known as Building Information
Modeling (BIM), as well as lean construction. 3) Almost every project makes use of BIM services.

Sample projects

Lake Champlain Bridge

Flatiron constructed the new Lake Champlain Bridge in northern New York State. The new two-lane steel arch-span structure replaces a structurally deficient two-lane bridge demolished in December 2009. Spanning Lake Champlain, the new 2,200-foot-long bridge reconnects Essex County, N.Y. and Addison County, Vt.

For two years, those travelling between the two counties relied either on a 100-mile detour around the lake or a ferry system initiated after the old structure was closed. Now that construction is complete, motorists can enjoy a delay-free crossing. The impact to the local community was the driving factor for the aggressive 490-day completion schedule.

John James Audubon Bridge

In 2011, Flatiron completed the longest cable-stayed bridge in North America, which spans a good 480 meters in length and is located near New Orleans. One special challenge in building the John James Audubon Bridge was the Mississippi River flood season. To enable the main span pier foundations to be poured, the HOCHTIEF company used a purposebuilt 2,300-metric-ton cofferdam construction. This saved both time and resources.

Port Mann Bridge

HOCHTIEF US subsidiary Flatiron was part of a joint venture team that built the new Port Mann Bridge in Vancouver between 2009 and 2013. The cablestayed bridge increases the Fraser River crossing’s capacity from five to ten lanes and reduces average travel times by 30 percent. In addition to the bridge itself, work also included upgrading a good 37 kilometers of Highway 1 on each side of the river. The new bridge will be financed by tolls.

Presidio Parkway

The Golden Gate Bridge is getting a new southern access route. The approximately 2.5-kilometer-long road which runs along the north coast of San Francisco, will open up access to historical and cultural landmarks and will be seismically far safer than the current access road which was built in the 1930s. The Presidio Parkway contract has a volume of around EUR 800 million and runs for 33.5 years. After completion the road will run from the toll station on the Golden Gate Bridge in the west to Broderick Street in the east.

The consortium, led by HOCHTIEF PPP Solutions North America, reached financial close on the project in 2012. HOCHTIEF’s US subsidiary will plan, build, operate and partially finance the project together with infrastructure fund Meridiam. Both partners have a 50 percent shareholding in the concession company, Golden Link Concessionaire.

Sustainability aspects were important right from the tender phase, as the project is endeavoring to earn a Greenroads Foundation certificate. On this project, all eleven mandatory “Project Requirements” are met. These include an end-to-end environmental approach, quality control, noise mitigation, and minimum air pollution. A huge amount of the building debris and waste is being recycled. Early on, a sustainability management plan was drawn up and an environmental manager appointed.

San Francisco Airport

Our US subsidiary Turner performed renovation and expansion works at San Francisco Airport’s Terminal 2 in a project phase that ran from 2008 to 2010. The boarding area was significantly upgraded, redesigned, and expanded, and new passenger loading bridges and baggage handling systems were installed. The work also included technical upgrades. Critical to the construction was maintaining the airport’s emergency communications center and air traffic control tower located above and adjacent to the work area. The purchasing experts at Turner Logistics provided supply chain management services for this renovation. This project is the first airport terminal in the United States to receive the U.S. Green Building Council’s LEED Gold certification.

Calaveras Dam

The Calaveras Dam is part of a system that provides drinking water to 2.5 million people in the greater San Francisco area. In 2001 the existing dam was deemed seismically unsafe and has been operating at less than full capacity ever since. HOCHTIEF subsidiary Flatiron has been working since 2011 to replace it with a stronger structure. During the course of the work, a total of 5.5 million cubic meters of rock and earth will be moved in order to construct the new dam, which will measure a good 64 meters high. The project also includes the construction of approaches and tunnels. When the replacement is complete, the old dam will be submerged underwater. Flatiron pursued a series of measures to minimize the environmental footprint, such as fish passages and constant monitoring of the air quality to prevent asbestos contamination.

ILM Transmission Lines

Our US subsidiary Flatiron has been working since March 2011 to build a new 255-kilometer transmission line in Canada. The 500-kilovolt line will run between Merritt and Vancouver, crossing topography that includes mountains, ravines, thickly-forested areas, and stretches of coast. Flatiron is building on a total of 620 sites along the route. The new overhead line is the first 500-kilovolt
line in Western Canada in more than 25 years. Most of the country’s grid dates back to the 1970s and now requires refurbishment
and upgrading.

John Jay College of Criminal Justice

The presence of train tracks under part of the John Jay College of Criminal Justice in New York led Turner to build the complex using an innovative structural system: The top nine floors of the building are hung from steel outrigger trusses that are supported by the stairwell, which is the building’s structural core. Innovation happens when you see every building as unique.

Burj Khalifa

It’s a skyscraper in the truest sense of the word: The Burj Khalifa in Dubai is currently the world’s tallest building and HOCHTIEF’s subsidiary Turner provided construction management for the project. Hotels, apartments, offices, and retail outlets are all housed there under one roof across 162 stories. At peak times, 12,000 people from more than 100 countries simultaneously helped in its construction. After 22 million man-hours of work, the building was completed in January 2010.

VietinBank Tower

The design of VietinBank Tower in Vietnam’s capital city of Hanoi is the work of Sir Norman Foster’s architectural team. During building of the tower, Turner will provide project management and construction supervision services. The complex consists of two towers 68 and 48 stories high. They will be home to the headquarters of VietinBank as well as a five-star hotel and serviced apartments. The seven-story podium will include conference facilities, a retail center, restaurants, and cafés. Lastly, a “green spine” concept will ensure innovative ventilation and energy supply for the building.

Husky Stadium

Turner renovated Husky Stadium in Seattle for the University of Washington in time for the start of the 2013 football season. The work included demolition and reconstruction of the lower bowl, lowering of the playing field to improve visibility, and construction of a club level, press box, and football operations support building, which houses the locker rooms, weight rooms, team meeting and event rooms, player lounge, and coaches’ offices. The facility also includes a sports medicine clinic. Turner additionally built a 200-spot underground parking garage. The renovated football stadium now has 70,000 seats, 2,500 club seats, and 28 new suites.

Yankee Stadium

The New York Yankees moved into their new home in the Bronx built by Turner, our US building construction subsidiary, in 2009. Fifty-two thousand fans can now cheer for their favorite baseball team at home games and enjoy luxurious private loges, a Hard Rock Café, and a screen six times the size of the previous one. Turner provided both preconstruction and construction services and was also responsible for demolition of the original stadium located only one block north. Yankee Stadium won McGraw Hill Publications’ “Project of the Year” Award for New York Construction in 2009.

Whitney Museum

At more than 18,600 square meters, the Whitney Museum of American Art’s new location in New York’s Meatpacking District more than doubled its previous space. Spread over six floors above ground and two below ground, the new building includes gallery space, education and studio facilities, art-handling spaces, a restaurant, special events areas, and a museum shop. A large terrace affording fantastic views of the Hudson River and Manhattan skyline will be used for exhibitions and events. Turner handled construction management for the project.

Ruskin Dam

HOCHTIEF Group Company Flatiron is upgrading the Ruskin Dam and Powerhouse, which is 60 kilometers (37 miles) east of Vancouver on the Stave River in Canada. The dam, built in the 1930s, provides power to homes and businesses across British Columbia. Flatiron is now working on two separate contracts on the dam.

The first, started in June 2012, includes seismically upgrading the dam and the powerhouse by constructing new piers, installing new spillway gates, constructing a two-lane bridge and powerhouse superstructure upgrade, and installing a new powerhouse crane and elevator.

The second includes refurbishing the dam’s three generating units. Crews are conducting repairs and replacing a section of the penstock. They will also install a new intake gate systems powered by a new hydraulic unit. The aging dam still has most of the original controls and systems from the 1930s, so crews will also replace mechanical and electrical systems.

Crews are faced with tight quarters at the intake, within the powerhouse and spillway tunnels, but also on the face of the dam itself. Crews use engineered platforms to do all the demolition, drilling and new pier construction on the spillway. The project requires close coordination with the plant operators—the existing facility must remain online and active during construction.

The area around the dam is used for recreation and includes some environmentally sensitive areas. The reservoir behind the dam is a drinking water source, and downstream of the dam thousands of salmon come to spawn every fall. Flatiron is following a comprehensive environmental management plan to ensure the area is protected.

Upon completion of the upgrades in 2017, the facility will be able to withstand a 10,000-year earthquake. The upgraded facility will provide power to 33,000 homes.

Buerger Center for Advanced Pediatric Care

HOCHTIEF Group company Turner Construction has constructed the Buerger Center for Advanced Pediatric Care at the Children's Hospital of Philadelphia. The building is a 12-story, 65,000-square-meter (700,000-square-foot) ambulatory care center with an adjacent, five-story, 1,500-space underground parking garage, and an expanded central utility plant. The Center houses various ambulatory care clinics supporting outpatient diagnostics and specialty care services. It is located beside the Colket Translational Research Building, which was also built by Turner.

Turner performed one of the largest excavations of its kind in the city of Philadelphia in order to prepare this site for the facility. Over the course of the nine-month excavation, the team excavated 21 meters (70 feet) down and hauled out roughly 229,367cubic meters (300,000 cubic yards) of rock.

In addition to building a world-class pediatric care facility, the project involved the construction of the largest green roof in Philadelphia, a sprawling 1-hectare (3-acre) landscaped plaza. Constructed on the roof level of the parking garage, the plaza incorporates local trees, shrubs, and flowering plants as well as four separate water fountains to create a setting that rivals a botanical garden. The plaza alone took nearly 145,000 man-hours to complete and includes 166 trees, 3,635 shrubs, 16,366 perennials, 4,587 cubic meters (6,000 cubic yards) of planting soil and stone mix, 2,787 square meters (30,000 square feet) of stone pavers, and 929 square meters (10,000 square feet) of stone cladding.
